内容説明 Concentrates on the often neglected but useful aspects of hydrogeological mapping. Covers geophysical survey methods and the importance of water chemistry as a tool in tracing the route of subsurface water， and goes on to lay a basic foundation in subjects needed for practice in the field: stratigraphy， structural geology， mineralogy， petrography， and geochemistry. Also covers basic disciplines and techniques indispensable for geological mapping， e.g.， cartography and surveying， geophysics， drilling， soil science， hydrology， and botanics. Written from a uniquely practical standpoint.
